Peat Mining An Initial Assessment Of Wetlands Impacts …

The calcium content of ground water commonly exceeds 30 mg/1, while that of preci- pitation ranges from 0.3 to 2.0 mg/1 and surface and interflow from 2.0 to 10 mg/1 (Verry and Boelter 1978). Calcium reacts with carbonic acid from rain to form calcium bicarbonate, which buffers most natural waters to yield pH values of 6 to 8.
